Subsonic ammunition is a great way to target shoot comfortably. Imagine NOT needing hearing protection on a humid 100 degree day? Target shooting with subsonic ammunition is also a terrific way to practice shooting long ranges with supersonic ammunition. Shooters can utilize the dramatic drops in the trajectories of subsonic bullets past 100 meters to simulate the sort of drop seen by supersonic bullets past 1000 meters. Shooters with a proper backstop can easily target shoot subsonic ammunition in their back yards without disturbing their neighbors.
